Which of the following is an example of a modifiable risk factor?

Modifiable risk factors are lifestyle-related factors that individuals can change to reduce their risk of developing certain health conditions. Smoking is a clear example of a modifiable risk factor because individuals have the ability to quit smoking, thus significantly lowering their chances of developing related diseases such as lung cancer, heart disease, and respiratory issues.

While obesity also qualifies as a modifiable risk factor since individuals can engage in healthy eating and exercise to change their weight, smoking is often highlighted specifically due to the high impact of cessation on overall health. Genetic predisposition and age, on the other hand, are non-modifiable factors, as people cannot change their genetic makeup or how old they are. Therefore, the focus on smoking exemplifies a direct lifestyle choice that can be altered to enhance one’s health.
